The nudity itself isn't sexual from what I've seen, so it would probably be alright with warning, but some people might get more huffity-puffity about it than others. (It's weird... often a scantily-clad chick can be a lot more sexual than a nude woman, and yet everyone only seems to fuss about the nude...

) But yeah, it's still questionable anyway because of detail.
As for the violence, if you're planning to cut out the violent parts then you might be ok. Your wording was rather confusing there... ^_^;;
Just think of how you'd do your scenes; would it be PG, PG-13, R, or NC-17 in the theater? Anything on Local should be PG-13 or lower.
Good luck!
